Smart Switch is a device that allows users to control their home lighting and appliances remotely. It connects to a Wi-Fi network, enabling users to turn devices on or off using a smartphone app or voice commands through virtual assistants like Amazon Alexa or Google Assistant. These switches can be installed in place of traditional light switches and often come with features like scheduling, dimming, and energy monitoring. This technology enhances convenience and energy efficiency, making it easier for users to manage their home environment from anywhere.
